SPEGIFIGATION forming part of Letters Patent No. 745,337, dated December 1, 1903.

Application filed- April 1903- Serial No. 150,593- (No model.)

To aZZ whom it mag/concern:

Be it known that I, ERNST ELIs FRIDOLF FAGERSTRGM, a subject of the King of Sweden and Norway, and a resident of Snndbyberg, in the county of Upland, in the Kingdom of Sweden, have invented certain new and useful Improvements in Reversing Gears, of which the following is a specification.

The present invention relates to a device for reversing the direction of rotation of a shaft driven by asteam-turbine or other motor. In the accompanying drawings such a deviceis illustrated as applied to a steam-tn rbine and suitable for use in boats, &c.

Figure 1 represents an elevation, and Fig. 2 a plan view.

The steam-turbine wheel or motor a, which always revolves in the same direction, has a lings e, by means of which one or the other of the gears 61 d can be connected with the shaft f, thus causing said shaft to revolve in one direction or the other. When the coupling-lever is in its middle position, Fig. 2, the couplingis-disconnected from the two gears, which will then revolve freely on the shaft f without imparting any motion to it.

' ed on the shaft f, a coupling device for connecting either of the said worm-gears with the shaft and two worms or screws gearing with the worm-gears and being each arranged on or connected to either of two shafts b, b gearing with each other the one of said shafts obtaining its motion from a motor.

In witness whereof I have hereunto set my hand in presence of two witnesses.
